This invention aims to provide novel means for supplying a charge of warm moist air through any desired part of the fuel inlet system of an internal combustion engine.

It is within the province of the disclosure toimprove generally and to'enhance the utility of devices of that type to which the invention appertains.

With the above and other vobjects in view which will appear as the description proceeds, the invention resides in the. combination and arrangement of parts and in the details l Figure 1;

of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1l shows in elevation, a device con-V suction.

The device forming the subject matter of this application includes a delivery chamber 2 and a mixing chamber 1. Fach of the chambers 1 and 2comprises a tubular body 3, on the ends of which caps 4 are detachably threaded. A quantityof filtering material 5 may be mounted inthe mixing chamber 1, there being as much or as little of the filtering material as'occasion may demand. Near to their" upper ends, the mixing chamber 1 and the delivery chamber 2 vare joined by ay connection 6 the bore of which isv governed by a valve 7 under the control of an operator and threaded into theconnection 6.

An arm 8 communicates with the mixingchamber 1 near to the lower end of the miX- ing chamber, the boreof the arm being under the control of a valve 9, constructed preferably like the valve 7. A pipe,10.is ]oined by a union 11 through the arm 8and isadapted to supply moist rair to the mixing'chamber1V by way of the arm 8. The pipe lfmay receive moist air from the overflow pipek of the radiator lof an internal combustion engine' (not shown)l or from any other appropriate source. Near 'to its lower end, a mixing chamber 1 has an arm 12 in which operates 192e. seriaiNo. 114,022.

pipe 16 delivering the warm air into the mix-- ing chamber 1 through the arm 12.l The air in the pipe 16 may be warmed from the eX- haust or in any other suitable way.

A valve 17 slides in thetubular the delivery chamber 2 and includes a tapered part 18 received in one end of the bore of the connection 6. The valve 17 is provided at its outer end with a transverse head 49 Vcarrying a connection 19 whereby the valve 17 may be operated in consonance with the operation of a carburetor, by thethrottle', or otherwise. A 'discharge pipe 20 is'connected by a union 21 to -a nipple 22 on the lowerportion of the tubul'lar body of the delivery chamber 2. The Y pipe 20 may discharge into the intake manifold of an internal combustion engine.

' The device operates responsive to 4engine The amount of moist air supplied is'regulated by the valvef9, and the amount of hot airv supplied is governed by the valve 14. The moist air and the hot air niiX in the chamber 1 and pass V upwardly through the filtering material. The air, then passes through the connection 6, a fixed adjustment being affordedby means of the valve 7, and it being possible to manipulate the valveto cut olf .the iiow of air through the connection a @Price-.11

body 3 of f -6 entirely. The connection 19 and the head 49 move the valve 17 different amounts, depending upon the speed at which the engine is running, this observation being true beto some part of the fuel control of the carburetor." When the valve 17 is shifted as aforesaid, the tapered part 18 of the valve'17 is moved in the bore of the connection 6,v and cause the rod 19 is connected to the throttle or more or less of the mixture of hot air and moist air passes into the delivery chamber 2, v

the'mixture of moist air and hot air passing lby way ofthe pipe 20 to the place of which, generally, is the intake manifold of an inter,- nal combustion engine. v

affords an edective means whereby a' supply of moist and hot air, duly, governed, may be Adelivered intol the fuel line of an vinternal combustion engine.`
